What are the differences between shell-type and core-type transformers?
Abhishek Rai, Marketing and Sales Manager
ABB's answer
The main difference is that in core-type construction, the windings surround the core. In shell-type construction, the magnetic core surrounds the windings so there is essentially no gap between the active part and the transformer tank walls. Due to that inherent robustness, shell-type transformers tend to be suitable when low impedance and/or high short circuit capability is required. ABB builds both technologies.
